General Description
TDA21301 is a multi-phase DC-DC buck converter controller integrated all control functions for the next generation GHz CPU
voltage regulator. TDA21301 automatically controls 2 to 4 interleaved buck switching power stage operation. The multi-phase
architecture is able to provide high output current with lower power dissipation on the switching devices and minimizing the
input ripple current and output ripple voltage. The equivalent high operation frequency optimizes the voltage regulator design
for better transient response and thermal performance.
TDA21301 utilizes the DCR of the output inductors in every channel as the current sense element. The differential current
sense in every channel results precious channel current information to the controller for good droop adjustment, channel
current balance, channel switching devices thermal balance and over current protection. The offset error caused by individual
differential current sense amplifier can be eliminated due to that the multiplexer is use to select the different channel current
sense signals with single differential current sense amplifier.
